What is the status of patent protection?

Legal analysis: patent maintenance refers to the process that the patentee pays a specified amount of maintenance fee to the patent management department in accordance with the law during the legal protection period of the patent to keep the patent valid. Patent maintenance time refers to the actual time from the date of application or authorization to the date of invalidation, termination, revocation or expiration of the patent.

Legal basis: Article 43 of the Patent Law of People's Republic of China (PRC) stipulates that the patentee shall pay the annual fee from the year when the patent right is granted. Article 44 In any of the following circumstances, the patent right shall be terminated before the expiration of the time limit: (1) Failing to pay the annual fee as required; (2) The patentee waives his patent right in writing. Where the patent right is terminated before the expiration of the time limit, it shall be registered and announced by the patent administration department of the State Council.
